"It's more convenient for me to [losslessly] stream* than it is to walk over to my shelves, find the CD and put it on. It has the added benefit that artists that I like make a bit more money out of it."
You may think that. In some cases it may even be true. In others, you need to know who "owns" the songs before you know who gets the money. Since the Beatles have been mentioned, Sony get the money for those albums/tracks.
